Neil Gorsuch is reportedly not happy with the US president's comments.

US president Donald Trump's comments about the judiciary during the travel ban row have been described by his own Supreme Court nominee as "demoralising and abhorrent".

Neil Gorsuch, who was named as the president's Supreme Court pick on 1 February, allegedly made the comments during a private meeting with senator Richard Blumenthal.

"He certainly expressed to me that he is disheartened by the demoralising and abhorrent comments made by President Trump about the judiciary," Senator Richard Blumenthal said in comments reported by The Washington Post that were confirmed by one of the judge's aides.
